University of Toronto researchers develop new cloaking technology

There are a lot of reasons to want to make things invisible, other than it just being incredibly cool. There are the many potential military uses of cloaking technology, of course, but it could also help improve cellular signals by hiding objects that would normally block and weaken signal strength.

Cloaking technology is popular science fiction trope, but real scientists have been researching and developing new ways to make cloaking objects a reality for years. Most recently, two researchers at the University of Toronto have found a new way to cloak an object using tiny antennas.

In a paper published this week in the journal Physical Review X, they describe their new take on cloaking. They're not making objects invisible to the human eye but making them undetectable by radar. They can even control the signals bouncing back to make objects seem larger or smaller than they really are.
